Abstract: Lizhouao ancient tomb in Jing’an county of Jiangxi is one of China’s top ten archaeological discoveries of 2007. The tomb was built at middle to late of the Spring and Autumn Period. Many wooden relics have been excavated from this tomb, including 47 coffins. 86 wet-wooden samples were collected from this tomb. All coffin woods were identified as Chinese fir(Cunninghamia lanceolata), except coffin G44 which was phoebe(Phoebe sp.). The physical and mechanical properties show that excavated Chinese fir has similar density with modern wood of Chinese fir; the MOR and MOE is 65% of modern wood. The degradation of excavated wood is relative low, which is related with the buried condition. The degradation might be effected by the pH of soil and hydration, other than fungi and bacteria. This research can support to further conservation and protection of cultural relics.
